Reply to How exactly does ocean acidification inhibit the formation of calcium carbonate in marine organisms? by fr140
I think its basically this: excess CO2 + water=acidic water the more CO2 the more acidic. Acidic water + calcium carbonate can then form calcium bicarbonate which is more soluble in water than calcium carbonate & calcium carbonate shelled beings like clams,coral etc start to suffer from the above reactions.

doesn’t untreated syphilis have its own two cents when it comes to brain function?

Probably a good thing you don't remember it. I remember alot of when I has covid, specifically that my body was was in pain for about a week until my room mate, who had lesser symptoms than me said "maybe you should go to a hospital". The whole time I also had these incredibly strange dreams that I was flying around new york city for some reason... also about a week after the hospital visit I had to drive (in a stick shift no less) and pick up 3 boxes of honey bees for my very first season, and I definitely remember thinking I should not be driving, but I had to. Miraculous that I didn't hit anyone or run any red-lights.. that I know of.

Any idea why this happens?

Reply to What exactly does Spaghettification mean? by mark0136
Yes the molecules are being pulled apart due to the stronger gravity closer to the black hole. Space-time stretching may have some effect in the last millionth of a second before the object is pulled in, but the object will already have been spaghettified before that happens.
Here’s a bit of math to back that up:
a=G*M/r2
Acceleration = gravitational constant * mass / radius(distance to mass center) squared
G=6.7e-11
Earth check:
M= 6e24
r=6378000m=6.4e6m
a= 6.7e-11 * 6e24 / 6.4e6^2 = 9.8m/s^2
3 solar mass black hole:
M= 6e30
r_feet = 1000000m (your feet at 1000km away)
r_head= 1000002m (your head)
a_feet = 402,000,000 m/s^2
a_head = 401,998,392 m/s^2
Looks almost the same but your feet are being pulled away from your head at 1608m/s^2 , or 164x Earth gravity! You’re also going close to speed of light and have only a few milliseconds left to live.
Above is Newtonian math and is good enough to answer your question. Even if you’re going 99% the speed of light, spacetime dilation is only 14%:
γ = √(1 - v²/c²) — Lorentz factor
= √(1 - 0.99²) = 14%

As well your jaw never really stops growing, it just slows down a lot, as well as joint degeneration and remodeling results in the mandibular (lower) front teeth being forced against the upper front teeth, and usually the lowers buckling resulting in the lower crowding you see (especially in men as they tend to show lower teeth a lot more than women) in older males. I'm looking at you Will Ferrell. Retainers keep the teeth in the same relative position as the bone moves around them

There’s, like, 10 days in my COVID experience that I don’t even remember. I had it pre-vaccine and it was brutal.

How would you fall through the event horizon without noticing? Your feet would be causally disconnected from your head (e.g. a nerve signal from your feet wouldn't be able to cross the event horizon to reach your brain), surely that would be noticeable? I guess my question is how can you remain a coherent object when no information can be sent radially outwards to the rest of you?

Bone is not totally rigid like cement is. It has a little bit of flexibility. This feature is very important for our survival.
